EUA2011A - 2.5-W Mono Filterless Class-D Audio Power Amplifier

Datasheet Summary

Description

The EUA2011A is a high efficiency, 2.5W mono class-D audio power amplifier.

A new developed filterless PWM modulation architecture further reduces EMI and THD+N, as well as eliminates the LC output filter, reducing external component count, system cost, and simplifying design.

Low EMI, Ultra-Low Distortion, 2.5-W Mono Filterless Class-D Audio Power Amplifier DESCRIPTION The EUA2011A is a high efficiency, 2.5W mono class-D audio power amplifier. A new developed filterless PWM modulation architecture further reduces EMI and THD+N, as well as eliminates the LC output filter, reducing external component count, system cost, and simplifying design. Operating in a single 5V supply, EUA2011A is capable of driving 4Ω speaker load at a continuous average output of 2.5W/10% THD+N or 2W/1% THD+N. The EUA2011A has high efficiency with speaker load compared to a typical class AB amplifier. With a 3.6V supply driving an 8Ω speaker , the efficiency for a 400mW power level is 84%.
